Sorry, it took some time b4 learning how to do ^this... on page 13 there’s an example in the middle of my post when I quoted tepples:

edit: If it’s too much work, don’t worry about “fixing” that it is just uncomfortable.

Hi... just wanted to point out that since the quote code has been “-mark-lessed, all of the effort that was used to color the non-username parts of (or add urls to) the quote title has been turned into hard to understand massive amounts of text. Maybe, could someone add a date consideration to the b...

This post tries to elaborate on these responses. :) Individual background tiles can not be moved around like sprites (otherwise they would be called sprites not background tiles) so there are no overlapping of background tiles, or is it just too annoying to keep it from overlapping a tile with a dif...

Only the best emulators include a "blow on the cart" option.

Have never stumbled across that best emulator option in Mesen... Sour, this is disappointing

If you have a hidden name table, and a hidden pattern table, the order of the updates doesn't matter at all. You just have to make sure that all VRAM updates take place during vblank or when rendering is turned off. Ahha! Yes! Thank you for helping clear my muddied thinking. :) Half of my brain was...

Hmm... so the proper way to change CHR tiles is to first draw the entire new screen with the wrong CHR tiles, and then write the new CHR tiles, then switch to the new screen’s nametable and finally adjust $2000 to display the background with the new CHR tiles? Whether you're gonna update the name t...

I’m unable to remove/edit that line bc Mesen always gives a long message that starts with, “An unexpected error has occurred.” Thanks, this should be fixed in the latest dev build now. You’re welcome. :) Thank you so much Sour; using 0.9.9.13 now, it’s much smaller than 0.9.9.0 :D; am now able to f...

Sour, or anyone else, how can I remove a mistyped Watch entry? I typed [9C,2] , but I’m unable to remove/edit that line bc Mesen always gives a long message that starts with, “An unexpected error has occurred.” So, now there’s an immovable line with a red “<invalid label>”; all it needs is a ‘$’; th...

Thank you tokumaru! :D (Going to try your #2 option/suggestion.) Yeah, I'd probably go with that too. And make it slightly more flexible even, by always writing an RTS after the last transfer, and remembering that position in order to restore the LDA once the transfer is done. That way the routine ...

tokumaru, this is my lack of experience response: But pla is 4 cycles. That’s twice as many cycles as lda #. You're right, lda # is indeed as fast as it gets - I didn't know you were doing that. Few people use that for VRAM transfers because of how much memory it needs (5x the amount of actual data...

Thank you tokumaru! :D (Going to try your #2 option/suggestion.) I didn’t want to block VRAM transfers... just wanted to add a beq to the end of the VRAM transfer function to skip the final 8 bytes written. :) I agree that it is pointless to wish for a change, but, for me, that makes the message mor...

tokumaru, this is my lack of experience response: But pla is 4 cycles. That’s twice as many cycles as lda #. How does a double amount of cycles make your solution more efficient? 8 extra bytes bc: 1 4kb CHR file is 4096 bytes. (4096 bytes / 256 tiles = 16 bytes per tile.) 4096 / 12 frames = 341.3333...

While writing CHRRAM, our code overflows by 8 bytes... is there a simple way to branch past the last 8 bytes written if $2007 becomes able to write to a #$00 low-VRAM address? I’m currently thinking about setting v if our function is writing to the last possible page of memory for CHR writing, and a...
